Komatsu launches new environmentally friendly dozer

Komatsu has released the new D61 EXi/PXi-24 dozer, adding to its range of intelligent control dozers.

The dozer is environmentally friendly, featuring a 6.8L, 125kW, SAA6D107E-3, EPA Tier 4 Final emissions certified engine. It provides a high level of performance while reducing both fuel consumption and operating costs.

It offers automated operation from heavy dozing to fine grading. The lack of blade mounted components and sensors means there is no need for operators to climb on the blade to install or remove global navigation satellite system (GNSS) antennas, no coiled cables to snag, and no electrical connections to slow the start and end of every shift.

Other features include proprietary engine and hydrostatic transmission technology that improves machine efficiency; a choice between quick shift, three speed mode and a variable 20-speed customisable transmission mode; a 17.8 cm, multi-lingual, high resolution LCD monitor with Ecology Guidance that helps operators observe machine performance for and follow real time integrated diagnostics for troubleshooting without a laptop; and a standard rear-view monitoring system that promotes increased operator awareness of potential worksite hazards.

Product manager at Komatsu, Sebastian Witkowski, said, “From first to last pass – rough cut to finish grade – the machine senses blade load, minimises track slip, and ensures operators get the most from every push.”

“Also, eliminating the need to install or remove blade mounted sensors each day not only saves on wear and tear and the potential for downtime, it saves operators valuable time that can be used to run the machine longer.”
